Root Cause Analysis: Going Beyond Symptoms

Root cause analysis (RCA) is a systematic process for identifying the underlying causes of problems. It is used in a variety of industries, including software development, to solve bugs at their source.

RCA goes beyond identifying the immediate cause of a problem to find the root cause, which is the underlying problem that is causing the bug. This can be a complex process, but it is essential for preventing the bug from recurring.

Advanced approaches to root cause analysis

There are a number of advanced approaches to root cause analysis. Some of the most common include:

  1. Why is my application crashing?
  2. Why is the application trying to access a memory location that does not exist?
  3. Why is the application’s memory map incorrect?
  4. Why did the application’s memory map become incorrect?
  5. Why did the application’s memory map become incorrect in the first place?

How to conduct an RCA

To conduct an RCA, you should follow these steps:

  1. Define the problem. What is the bug that you are trying to solve? What are the symptoms of the bug?
  2. Gather data. Collect as much data as possible about the bug. This may include logs, interviews, and physical evidence.
  3. Analyze the data. Use the data that you have collected to identify the potential causes of the bug.
  4. Identify the root cause. Use the five whys, fishbone diagrams, FTA, ECA, or another RCA technique to identify the root cause of the bug.
  5. Implement corrective actions. Take steps to fix the root cause of the bug.
  6. Verify the fix. Test the application to make sure that the bug has been fixed.
